Detailed Description

TM6605 Linear Resonant Actuator (LRA) Haptic Driver.

The TM6605 from Titan Micro Electronics is an I2C-controlled haptic driver for LRAs. It exposes 44 pre-programmed effects selectable by ID and is controlled by writing two registers (effect select and playback control). The I2C interface is write-only.

Enumeration Type Documentation

tm6605_effect

enum tm6605_effect

#include <tm6605.h>

TM6605 pre-programmed effect IDs.

Valid effect IDs that can be written to the effect-select register. Approximate durations (in milliseconds) are taken from the datasheet and are reference values; actual playback time depends on the LRA.

Function Documentation

tm6605_select_effect()

int tm6605_select_effect	(	const struct device *	dev,
		enum tm6605_effect	effect )

#include <tm6605.h>

Select the haptic effect to be played by the next start_output call.

The TM6605 effect-select register is loaded but playback is not started. Call haptics_start_output() afterwards to trigger the effect.

Parameters

dev	TM6605 device instance.
effect	Effect ID (see tm6605_effect).

Return values

0	on success.
-EINVAL	if effect is not a valid effect ID.
-errno	from the underlying I2C controller on failure.
